Special Issue Information

Dear Colleagues,

The development of polymeric materials has accelerated in the last decade due to their exceptional characteristics (e.g., chemical resistance, no need of post-treatment finishing, thermal and electrical insulation, more lightweight than typical metals by up to a factor of 10, naturally radar absorbent, easy to clean and sterilize (medicine)). Nevertheless, in order to sustain and develop these strengths, it is necessary that researchers make constant efforts in order to respond to the increasingly varied demands of society. For this reason, the characterization of polymeric materials in terms of intrinsic properties (physical, chemical) as well as use (mechanical, technological) is indispensable in order to make recommendations for use in various areas of activity.

The present Special Issue on “Crystallization and Properties of Polymeric Materials” welcomes contributions in the form of full articles, short communications, or review articles on topics related to the design, characterization, surface modification and processing of polymers and/or polymer composites for use in applications ranging from aircraft, aerospace, and sports equipment to organic polymers used in water purification and 3D-printed parts. This Special Issue represents a good opportunity for engineers, chemists, and physicists to put together different aspects of their research that aims to control complex and tunable functions in vitro and in vivo.

Polymers are becoming a very popular tool in the crystallization of different compounds. In this work, a new method of crystallization is proposed using stimuli-responsive star polymer in order to obtain hollow structure crystals. In these experiments, amphiphilic copolymer of acrylic acid (AA) and methyl acrylate (MA) were used for isohydric crystallization via they cooling of KCl in deionized water solution. The experiments were realized in quartz cuvette with a magnetic stirrer using a specialized spectrometer with precise temperature control. The crystallization course was monitored by the absorbance readings and analysis of the nucleation energetic effect. It was proved that the moment of the polymer’s phase transition occurrence had an important role in the crystal growth process. On the other hand, the occurrence of phase transition did not trigger the nucleation. The supercoolings achieved in the presence of the polymer were significantly higher compared to pure salt crystallization. On the basis of analysis of Particle Size Distribution (PSD) and Critical Aggregation Concentration (CAC) of the polymer, it was proposed that the hydrophobic particles of macromolecules created from polymeric aggregates served as templates for the formation of hollow crystals. Their purity was verified using thermogravimetric analysis (TGA), 1H NMR, and XRD. Only trace amounts of polymer were found in the crystalline product. Full article
